You pick! The pros disagree on where Galium album and the very similar Galium mollugo grow. Michigan specimens were all redetermined as G. album a while back. If you go with one version, G. album only grows in CT and MA, and G. mollugo is spread across much of this continent. The true ranges seem to be somewhat less for G. mollugo, and more for G. album. Both species are also called hedge bedstraw or false baby's-breath.
